Is Prima Luna evo 300 a good preamp for parasound a21+?

I go with the don sachs as well. Great recommendation. 

The Don Sachs looks a bit of a bargain. If I was in the market for a new pre I would grab it.

Thanks

The PL would probably be fine, but given what you’re looking for I’d hop on this Don Sachs preamp no question.  Best of luck.

From 1500.00 to 3000.00 new or used.   Thanks

What’s your budget, and are you looking for new or used?

The speakers in Sonus Faber Venere 3.0.

I am using Arcam SA 20 integrated amp. The sound I am looking for is a soft rich vibrant sound.  Thanks

Completely depends on what sound characteristics you’re looking for.  What preamp are you using now, and what improvements are you seeking?
